Slightly off topic, but if we're talking about simplicity...

why are people still using this doctype:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

instead of the beautifully simple HTML5 doctype:

<!DOCTYPE html>

I get that people might use the old doctype out of habit, but it's such an ugly, unnecessary habit, and it would probably be smart to work on discarding it. At the very least, we should be making sure that new developers learn the new doctype.
